Apps for a Testing Environment

This is the GitLab Support Team’s collection of information regarding testing environments, for use while troubleshooting. It is listed here for transparency, and it may be useful for users with experience with these tools. If you are currently having an issue with GitLab, you may want to check your support options first, before attempting to use this information.

noteThis page was initially written for Support Engineers, so some of the links are only available internally at GitLab.


The following were tested on Docker containers running in the cloud. Support Engineers, please see these docs on how to run Docker containers on dev-resources. Other setups haven’t been tested, but contributions are welcome.


Please see our Docker test environment docs for how to run GitLab on Docker. When spinning this up with docker-machine, ensure you change a few things:

  1. Update the name of the docker-machine host. You can see a list of hosts with docker-machine ls.
  2. Expose the necessary ports using the -p flag. Docker normally doesn’t allow access to any ports it uses outside of the container, so they must be explicitly exposed.
  3. Add any necessary gitlab.rb configuration to the GITLAB_OMNIBUS_CONFIG variable.

For example, when the docker-machine host we want to use is do-docker:

docker run --detach --name gitlab \
--env GITLAB_OMNIBUS_CONFIG="external_url 'http://$(docker-machine ip do-docker)'; gitlab_rails['gitlab_shell_ssh_port'] = 2222;" \
--hostname $(docker-machine ip do-docker) \
-p 80:80 -p 2222:22 \


SAML for Authentication

We can use the test-saml-idp Docker image to do the work for us:

docker run --name gitlab_saml -p 8080:8080 -p 8443:8443 \
-d jamedjo/test-saml-idp

The following will also need to go in your /etc/gitlab/gitlab.rb. See our SAML docs for more, as well as the list of default usernames, passwords, and emails.

gitlab_rails['omniauth_enabled'] = true
gitlab_rails['omniauth_allow_single_sign_on'] = ['saml']
gitlab_rails['omniauth_sync_email_from_provider'] = 'saml'
gitlab_rails['omniauth_sync_profile_from_provider'] = ['saml']
gitlab_rails['omniauth_sync_profile_attributes'] = ['email']
gitlab_rails['omniauth_auto_sign_in_with_provider'] = 'saml'
gitlab_rails['omniauth_block_auto_created_users'] = false
gitlab_rails['omniauth_auto_link_ldap_user'] = false
gitlab_rails['omniauth_auto_link_saml_user'] = true
gitlab_rails['omniauth_providers'] = [
    "name" => "saml",
    "label" => "SAML",
    "args" => {
      assertion_consumer_service_url: '<GITLAB_IP_OR_DOMAIN>/users/auth/saml/callback',
      idp_cert_fingerprint: '119b9e027959cdb7c662cfd075d9e2ef384e445f',
      idp_sso_target_url: '<SAML_IP_OR_DOMAIN>:8080/simplesaml/saml2/idp/SSOService.php',
      issuer: '<GITLAB_IP_OR_DOMAIN>',
      name_identifier_format: 'urn:oasis:names:tc:SAML:2.0:nameid-format:persistent'

docker run -d --name elasticsearch \
-p 9200:9200 -p 9300:9300 \
-e "discovery.type=single-node" \

Then confirm it works in the browser at curl "http://<IP_ADDRESS>:9200/_cat/health". Elasticsearch’s default username is elastic and password is changeme.


See our Kroki docs on running Kroki in Docker.


See our PlantUML docs on running PlantUML in Docker.


docker run -d -p 8081:8080 cptactionhank/atlassian-jira:latest

Then go to <IP_ADDRESS>:8081 in the browser to set it up. This requires a Jira license.


docker run -d --name grafana -e "GF_SECURITY_ADMIN_PASSWORD=gitlab" -p 3000:3000 grafana/grafana

Access it at <IP_ADDRESS>:3000.
